Capt. Shawn O'Leary with the Sheriff's Office said the vehicle failed to negotiate a curve and hit a tree at a high rate of speed.

According to O'Leary, the driver was not wearing a seat belt and was pronounced dead at the scene. The passenger, however, was wearing a seat belt and was partially ejected from the vehicle. He was flown by Life-Flight to Central Maine Medical Center and is being treated for non-life threatening injuries.

Authorities have released the names of the victims.

O'Leary said the driver of the car, who was killed, was 17-year-old Joshua Bonnell of Haverhill, Mass. The passenger is 15-year-old Austin Bonnell, also of Haverhill, Mass.

O'Leary said Austin Bonnell suffered two broken legs and a concussion.

The Sheriff's Office is still investigating but said speed was a factor in the crash, but alcohol was not.
